PA 5260 httpd multiple processes running

L1 Bithead



These processes are seen to be utilising 400% of the CPU and seem to be a bug . Anyone else seen this on PAN-OS 10.1 ?

Hi @Ridwaan ,


Do you perform a lot of API calls ?

If you have a high API call rate, the web_backend process opens a lot of HTTPD child processes.


Although NGFW is able to manage until 25 HTTPD child processes, the amount of memory consumption per HTTPD can impact the behavior.


If you do you can try to reduce the number of API queries.

You can also try to restart the web-backend process to kill every child HTTPD process and free swapmemory and CPU.


 > debug software restart process web-backend


Hope this helps,
